FAN ATTACHMENT FOR ROCKING FURNITURE.

EEPECIPICATION forming part of Letters Patent No. 326,727, dated September 22, 1885.

Application filed May 2, 1885. (N model.)

To all whom it may concern.-

Be it known that I, WALTER DUNKERLY, of Providence, in the State of Rhode Island, haveinvented an Improvement in Automatic Fan Attachments for Rocking Furniture, of which the following is a specification.

My invention consists in the combination of a rocking chair or cradle with a weighted flexible fan and its attach ments, as hereinafter fully set forth.

Figure 1 is a perspective view ofa rockingchair with my improved automatic fan attached thereto. Fig. 2 is a perspective view of the metallic fastening, by means of which the fan is secured to the chair. Fig. 3 is a plan view of the screw-stirrup of the fastening. Fig. 4 isa detail view of the lower portion of the fan, illustrating the preferred attachment of the fan-controlling weight-bar to the lower edge of the fan. Fig. 5 shows an edge view of the fan when the lower edge of the same is loosely attached to the weightbar.

In the accompanyingdrawings, A is a rocking-chair. B B are curved wire standards for supporting the flexible fan-sheet O, which is secured to the cross-bar D, connecting the upper ends of the standards B B. The fansheet 0 is to be made of any desirable flexible material, (cloth or pa er being very suitable for this purpose,) and s provided at itslower end with an attached barwveight, E, which serves to impart the proper forcible vibratory movement to the fan-sheet in harmonious relation to the rocking movement of the chair or other article of rocking furniture to which the fan may be attached.

In adapting the bar-weight E to the flexible fan-sheet C,and attaching the same thereto, I prefer to bend or indent the bar, as shown at a a in Fig. 4:, the distance between the bends a a being somewhat less than the width of the lower edge, 0, of the flexible fan-sheet 0, so that the lower portion of the sheet when the corners m m are secured to the bar,as shown, will slightly bag under the opposing resistance of the air, thus serving to direct the air inward and downward at each vibration of the fan. The alternate inward curving of the loose lower portion of the fan-sheet, resulting from the described contracted attachment of the corners m m to the weight-bar, serves to prevent the air from escaping outward at the vertical edges n a when the fan is in rapid vibratory action,and is an important feature in my invention, although highly-desirable results may be secured when the flexible fansheet 0 is secured to the bar E in an outstretched condition.

In order to secure the standards B B to the chair, I provide a metallic-fastening attachment, F, which consists of the fastening-plate 0, provided with the slots (1 and e, which are adapted to receive the wire stirrupf, having at one end a head, 9, and at the other end a screw-thread and nut, h. The perforatedenlargement 2' at one end of the plate 0 is adapted to receive the wire standard B, which is secured therein by means of the screw j, or otherwise.

In attaching my improved automatic fan to a rocking cradle the standards, which serve to support the bar D, to which the weighted flexible fan-sheet O is attached, may be secured either to the side or head of the cradle, and the proper rocking movement of the same will-impart a corresponding vibratory movement to the weighted flexible fan, which will serve to impart rapid motion to a refreshing downwardlydirected current of air.

I claim as my invention 1. The combination, with a rocking article of furniture, of the flexible automatic fan secured to the said article of furniture and having its upper end outspread,while at its lower end the corners of the fan are brought nearer together and a barweight secured to the corners of the loose lower edge of the fan, substantially as described.

2. The combination of the weighted flexible fan 0, the standards B B, attachingplates 0, provided with the slots d and e, and the perforated enlargement 'i,adapted to hold the standard B, and the screw-strapf, adapted to enter the slots of the plate 0, substantially as described.

IVALTER DUNKERLY.
